Close any open Nautilus windows
Open Nautilus (View as Icons) and go to a directory with video files.
After a few seconds new video thumbnails should be automatically generated and appear!

Details

The "Totem Movie Player" that comes with a default install of FC4 is practically useless. When you remove the totem package and install the totem-xine package, you now have an excellent video player that actually works since totem-xine uses the Xine library as its backend video engine.

The totem-xine package contains a utility program called “totem-video-thumbnailer” which hooks into the gnome system and is automatically called by nautilus to generate video thumbnails. You can see the hooks in the Configuration Editor (/desktop/gnome/thumbnailers).

Now nautilus should be happy to generate preview images of your video files and show you nice thumbnails, right? Almost. There currently does not seem to be any mechanism for gnome to realize that you have added video thumbnailing capability. So how can we make gnome understand this?

That's where the ~/.thumbnails directory comes in. Your ~/.thumbnails directory is where Gnome applications store preview images (thumbnails) for file types they recognize such as PDFs or PNGs or JPEGs. This thumbnail cache is used to speed up subsequent thumbnail display in Gnome applications like Nautilus and gthumb by avoiding generating thumbnails again.

There can be three subdirectories of your ~/.thumbnails directory: normal, large, and fail. They may not all exist depending on how much file browsing you have done.

Before you installed totem-xine, gnome was unable to create video thumbnails for your video files, so it put entries in the “fail” subdirectory so it would know it need not try again next time you browsed those video files.

After you install the totem-xine package, video thumbnails can be generated, but gnome still sees entries in the "fail" directory so it doesn't even try. To force gnome to realize that you can now generate valid video thumbnails, you need to delete everything in the “fail” subdirectory.

Once you clear out the "fail" subdirectory, new thumbnails can be created and they will be placed in the "normal" subdirectory. Video thumbnailing should now work.

Well, I did a fresh FC6 install and removed totem right away, without replacing it with totem-xine.

Then, following your great instructions, I've tried to erase the fail folder and also installed totem-xine. But it didn't work yet.

In order to make the totem thumbnailer work I had to do a

Code:

yum -y install xine xine-lib xine-lib-extras-nonfree

Then I could both watch movies in totem and I got video thumbnails.

But I still don't have thumbnails for some of the s*ck*ng .WMV videos that people send me. I have the w32 codecs installed, as described here.

Some .wmv I'm able to watch in totem (those that also has a thumbnail). But some of them I cannot watch in totem (and also don't get a thumbnail). When trying to watch I get the message: The MS WMV 9 (win32) codec is not supported. You may have to install additional plugins to play some kind of videos..."

On the Desktop only:
* I installed mplayer-video-thumbnailer from Duli's link.

Is it possible mplayer-video-thumbnailer and totem-video-thumbnailer are conflicting?
Or perhaps I am using mplayer-video-thumbnailer incorrectly.
Are there more verbose instructions how to use mplayer-video-thumbnailer?
Any other ideas/suggestions?

Hello, I would advise you to have just one of them.

If you plan to have just mplayer-thumbnailer, be sure to remove totem and totem-xine and also other xine libraries (do a "yum list | grep -i xine" in order to chek what is installed).

Then, in order to get mplayer-thumbnailer working, download it from the link, unpack it and then run setup.sh as root. Then run gconf.sh as normal user. The gconf.sh will register the command lines that does the thumbnails in you configurations.

You may see the hooks in the Configuration Editor (/desktop/gnome/thumbnailers), to check if they are alright. You should see some "mplayer %u %whatever" in the configurations for mpeg, wmv etc.

That´s it. You may need to erase the foldes under .thumbnails in you home folder to refresh everything. And you´re good to go.

I personally don´t like totem or xine or totem-xine, that´s why I just use mplayer both as video player and thumbnailer. Works pretty well!

Oh...wait. When i right click on a video, it gives me an option to "Open with xine." But when I choose that option, nothing happens. Is it possible something was left over from the totem-xine install? and thus causing problems?

Sorry for th double post.

I don´t think so... Very unlike to have something to do with it. See the next post, please.
